How to get all nodes of a polygon (for buildings) with one known inside node
Hi everyone!
I'm now using OSMnx to extract data for buildings. What I need is the addresses for buildings along with their footprint data.
The question I met is about some of the buildings have multiple addresses, thus there are no address data for that building's polygon.
For example, the building 'Furutorpsgatan 49A' in (in Helsingborg, Sweden Sweden) has three nodes you can search for, which are:
Furutorpsgatan 49A; Furutorpsgatan 49B; Gustav Adolfs Gata 23
![alt text][1]
but if you export the geometry data (polygon), **there's no address data at all!**
I was trying to use OSMid for polygons to match the position, but I can't find the building with OSMid 'w483244917'
Then I'm thinking is there any method I can **export the polygon data through one or several nodes inside?**
Or could you suggest me some methods to get any building footprint polygons through building addresses?
Thank you!
